Once it is apparent that the cycle is ending, I will look to take profits.
So what metrics are you watching to identify when that cycle ends?? I believe the XP support ended in May..so a late Spring/Summer spike makes perfect sense...but I would think that would run it's course pretty quickly.
Also, another factor one would have to consider is that Intel is in the midst of a $4 billion buy-back "surge" this quarter...so that's undoubtedly providing some lift to the stock price that won't be there in future quarters.
